Bingo! Your /etc/udev/rules.d/65-xorg-wacom.rules file did the trick! I seriously wonder, though, why it hadn't worked before. The situation was that I had added the udev rules directly into /lib/udev/rules.d/69-xserver-xorg-input-wacom.rules.

When having it configured that way 'udevadm info
--path=/sys/class/tty/ttyS0/ --attribute-walk' gives

  looking at device '/devices/pnp0/00:08/tty/ttyS0':
    KERNEL=="ttyS0"
    SUBSYSTEM=="tty"
    DRIVER==""

  looking at parent device '/devices/pnp0/00:08':
    KERNELS=="00:08"
    SUBSYSTEMS=="pnp"
    DRIVERS=="serial"
    ATTRS{id}=="WACf004"

  looking at parent device '/devices/pnp0':
    KERNELS=="pnp0"
    SUBSYSTEMS==""
    DRIVERS==""

After cleaning up /lib/udev/rules.d/69-xserver-xorg-input-wacom.rules to
its original state and installing /etc/udev/rules.d/65-xorg-wacom.rules
from comment #12 the digitizer appears to be fully working. The mouse
cursor follows the digitizer. Mouseclicks work with both ends of the
pen. A brief test with xournal shows pressure sensitivity working as
well as the button on the pen. This is great. Thanks for the effort.

In case this is helpful to anyone -- this is how the logs look on my
Motion Computing LE1700, now that it's working:
